摘要:在对浙江九龙山自然保护区内的粉叶柿群落进行调查的基础上,分析了粉叶柿群落结构与物种多样性以及粉叶柿种群结构与分布格局等特征。结果表明:样地中共有维管束植物79种,隶属37科66属,单属种植物较多。植物区系具有热带起源性,是从热带向温带过渡的阶段。群落垂直层次分明,物种的丰富度指数、多样性和均匀度均为灌木层>乔木层>草本层。粉叶柿种群结构呈纺锤型,幼苗严重不足,种群有衰退的趋势。种群分布格局整体上呈集群分布,在不同发育阶段,种群分布格局有所差异:幼树为集群分布,中树和大树为随机分布,种群呈扩散趋势。这种差异与其生物学、生态学特性及与物种的竞争排斥作用有密切联系。
Based on the data collected from six sample plots in Jiulongshan Natural Reserves of Zhejiang Province, the community structure, biodiversity index, distribution pattern and age structure of Diospyros glaucifolia community were analyzed. The results showed there are 79 vascular plant species in plots, belonging to 37 families and 66 genera, many genera contain only single species. The flora that originated from tropical is a transition from tropic to temperate. The structure of D. glaucifolia community contained three obvious different layers. The species richness index, biodiversity index, evenness index were all in the order of the shrub layer 〉 the arbor layer 〉 the herb layer. The population structure of D. glaucifolia was a spindle type, and the population of D. glaucifolia descended due to lack of seedlings As to the distribution pattern of D. glaucifolia, generally speaking, the distribution pattern of the population was clump, but there still were some differences at various adult trees and big trees, and the population showed diffusing stages of development: clump for saplings, random for trend. The biological and ecological characteristics of the species and competitive exclusion principle led to such differences.
